CHAPTER IV RESULT OF THE RESEARCH AND DISCUSSION
A. Research Result
2. Description of Research Data
a. The Result of Pre-Test Score (Experimental Class)
The measurement of the writing skills of the eleventh grade research students used a pre-test before being given treatment. This study conducted a pre-test at the first meeting of this study to determine the students' initial knowledge about writing skills before being given treatment. The pre-test used in this research was in the form of essay writing.
The test was followed by 28 students. The highest score was 79 and the lowest score was 28 with the total score of 1550. The total interval class total of this results of the pre-test 6. It can be seen in the table below:

The Result of Pre-test Score
Furthermore, based on the table and graphic above, it can be concluded that 28 students as the sample of the research can be devided into six categories. First, the number of the students got score 28-36 that was 3 students or 10,7%. Therefore, the number of the students that got score 37-45 that was 6 students or 21,4%. Then, the number of the students that gort score 46-54 that was 5 students or 18,0%. Next, the number of the students got score 55-63 was 6 students or 21,4%. The number of the students got score 64-72 that was 2 students’s or 7,1%.

The last, the number of the students got score 73-81 that was 6 students or 21,4%. Moreover, the mean of the pre-test in the experimental was 55.14, the median was 54.5 and the mode was 77.9, 61.7, 38.75.
b. The Result of Post-Test Score (Experimental Class)
After analyzing the weakness and understanding of students’
ability on writing skills, the researcher conducted the treatment. Given the treatment, they have a good understanding of writing skills. They can analyze the feedback from Assessment Portfolio and then can practice their writing good criteria.
Furthermore, the researcher gave the post-test to know the students’ result narrative text on writing after treatment. The test was followed by 28 students. They highest score was 98 and the lowest score was 50 with total score 2371. The total of interval class of this result post-test was 7. It can be seen on the table of below:

7 49-56 1 3,5%
If the data was put into graphic, it can be seen as follow:

The Result of Post Test Score
Furthermore, based on the table and graphic above. Researchers want to present class interval data, which means that in the assessment process, students have several levels, it is concluded that 28 students as the research sample can be divided into seven levels. First, the number of students got score 49-56 was 1 students or 3,5%. Then, the number of students got score 57-64 was 0 students or 0%. Next, the number of students got score 65-72 was 0 students or 0%. Therefore, the number of students got score 73-80 was 3 students or 10,7%. The number of students got score 81-88 was 14 students or 50%, Then, the number of students got score 89-96 was 8 students or 28,6%. The last, the number of students got score 97-100 was 2 students or 7,2%. Moreover, the mean of the pre-test in the experimental was 85.8, the median was 82.8 and the mode was 83.32.

c. The Result of Pre-Test Score (Control Class)
The pre-test was administered in the firs meeting, and the researcher administered a pre-test to determine the previous students’
writing skills. The test was followe by 29 students. The highest score was 75 and the lowest score was 22 with the total score 1512. The total of interval class of pre-test was 7. It can be seen on the table below:
